Ofcourse, way it is desired to use the device.

A plate His bent to provide a It will be seen that the knuckle of the plate 2, 5raised portion having a vertical slot l2 in which as shown more clearlyin Fig. 3 of the drawing,

extends inwardly and around and back of the pintle l5 of the hinge, andthen outwardly and around until the end of the metal meets the body ofthe plate. With this formation, therefore, the plate 2, where itterminates in the said hinge, engages the edge 16 of the plate I, sothat said edge forms a fulcrum against which the plate 2 bears, with theresult that a considerable leverage is exerted, so that flexing orbending of the plate 2 is comparatively easy in order to force it intoposition to engage the retaining edge i3 of the latch-piece, so that thelatter will hold the hasp plate 2 under tension. This results in anoutward pull on the latch-piece 5, which may be called a strike-piece,and this tension tends to keep the door tightly closed when the hasp isin latching position, and tends to prevent rattling and accidentalunlatching of the hasp. Normally, as shown in Fig. 3, when the hasp isin latching position the plate 2 is spaced a distance from the raisedportion of the plate II, and the plate 2 is at an angle to the plate I,instead of being parallel therewith.

Furthermore, it will be seen that the knuckle 3 is formed by a reducedend portion of the plate 2 that extends around and behind the pintle I5and then in front of the latter until its end I! practically engages itsbase, so that the latter is in position to engage the fulcrum l6 shownand described.

What I claim as my invention is:

1. A combined hasp and latch device, comprising a bracket plate, aswinging hasp plate, a hinge between the ends of. said plates, and meansforming a stop at said hinge, to limit the swinging motion of the haspplate, so that in latching position the hasp plate is slightly flexedand under tension, said stop permitting flexing throughout the entirelength of the hasp plate, said hinge comprising a pair of spacedknuckles integral with said first mentioned bracket plate, with saidstop formed by an edge extending between the knuckles, and said haspplate having a single knuckle disposed between said spaced knuckles,with said edge engaging the inner side of said single knuckle.

2. A structure as specified in claim 1, comprising a pintle for saidhinge, said single knuckle being formed by an end portion of said haspplate that extends inwardly back of said pintle, in the latchingposition of the device, and then around in front until its endterminates at its base portion.

3. A structure as specified in claim 1, said edge being in the plane ofthe flat outer surface of. said bracket plate, and the point ofengagement of the hasp plate with said edge being in a plane parallelwith but spaced a distance from the plane of the fiat inner surface ofthe hasp plate.
